[DiabloD3]

I use Nvidia's ShieldTV server in the Experience package with Moonlight as the client, but yes, the Nvidia closed source backend does fault on some things (such as only shows primary monitor in multimonitor setups), but the stream quality is much higher and latency lower than using Steam to stream my desktop.

However, there is an alternative to Nvidia's closed source backend, called Sunshine (argh, the pun): https://github.com/loki-47-6F-64/sunshine

I haven't tried it yet, as I do run Windows /w Nvidia GPU on my desktop, but it apparently uses nvenc correctly (I'm on a Turing, Turing and Ampere have that fancy low latency mode for their encoder; something Steam still doesn't engage for in home streaming, yet uses the nvenc API directly), but also can support multimonitor (has a shortcut key to cycle through monitors).
